IMPROVEMENT IN LATH'MACHIN ES.

The Schedule referred to inthese Letters Patent and making part-of the same.

To whom it may concern:

Be it known that-I, JAMES HALL, of Alma, in the county of Gratiot and State of Michigan, have Invented. a new and useful Improvement in Machine for Manufacturing Lath and Dressed Lumber; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon, and being a part of this specification, in'which- Figure 1 is a perspective view of my apparatus.

Figure 2 is an end elevation of the same.

Like letters refer to like parts in each figure.

The nature of this invention relates to the construction of a machine for the purpose of dressing sheathing, .to be employed for building purposes, to a uniform thickness, and, at the same time, convert one bearing-rollers D.

Arranged so as to have a vcrtical motion, when required, is the sash E, within the frame A, in 'rear of the surfacing apparatus.

This sash'works upon slides within the frame, and is adjusted to'any desired height by means of the screw F, or its equivalent for the purpose.

To the top of this sash is journaled the mandrel H, to which is attached a series of circular saws,.I.

In fi'ame houses it is customary to sheath up the inner sides of the walls with boards, upon which the lathis nailed to receive the plaster. The device above described isdesigned to first dress said sheathing-boards to a uniform thickness,- and in its passage through the'plauer to present it to the series of saws, which cut a series of ganes or rabbets upon the under side of the board at any distances apart that may he desired, and of snfficientdenth for the purpose of holding the plaster.

In a detached view I show a sectionof a piece of sheathing prepared ready for use by this apparatus.

By the employment of sheathing thus prepared the necessity of lathing is obviated, and great economy secured in the construction of frame houses.

Other bearing-rolls may be added to the machine;

if found necessary, in the rear of the mandrel and saws, to hold the boards while the rabbets are being sawn.

Instead of using saws, as above described, cutters of a proper shape may be employed, whi ch will answer the same purpose.

.I expressly disclaim any surfacing or planing-machine; but

' What I claim as my invention, and desire to se-' cure by Letters Patent, is-

In combination with theplaning-machiue AB C D, thegrooving device described and shown, consisting of the. sash E, the mandrel H, the saws I, and adjust-:

ing-screw F, wh'en construoted'and arranged as de scribed and shown, and as and for the purposes set forth. Witnesses; JAMES T. HALL.
